That part looks like a buffer for the hammer? What's it made of?

Dieseljayy, with so many rounds downrange, what have you found to be the best cleaning interval for the gas valve?

Thank you

Cleaned it once around 6-7k. But I have pulled the piston out to its extended position and cleaned the caked on residue on the shaft of the piston after ever range session. (not disassembling the housing though).

I thought being able to accept AR triggers was a design feature. Now we are supposed to accept the crappy trigger in a $1500 gun? Right.

Thanks Sig. But I'm going to start looking elsewhere.

MPX Trigger Compatibility

The SIG MPX has a fire control group specifically designed to accommodate the high impulse of the MPX operating system. The MPX Trigger Bridge (indicated below by arrow) is in place to reduce wear and extend the life of the factory installed fire control components. Removal of the Trigger Bridge is NOT recommended and will void the warranty of the firearm. While the SIG MPX fire control components are similar to the AR15 platform, and aftermarket fire control components may fit, installation is NOT recommended in the SIG MPX. Doing so may result in damage to the MPX proprietary fire control components or the aftermarket components you installed.

Given IMO that many folks will like a lighter trigger, I expect that someone will come up with the trigger mode and "bridge". Either SIG can do it or we can wait until Geissele gets one ready?
By the way, so far the after-market (other than picatinny furniture) AR15 opportunities for MPX are getting fewer and fewer. On the other hand, the opportunity is wide open for firearm entrepreneurs to make money .

What does the bridge protect ???? Yes I know it stops overtravel of the hammer. But whats damage is caused by hammer overtravel ?

This issue is also being discussed over in the pistol section, since the MPX is also a pistol.

I wrote a blog article about the issue:

and also shot a video last night that shows part of the problem with aftermarket triggers if you try to keep the trigger bridge in place.

Good to know. Thanks!

Does anyone have a pic of the current collapsible stock they just got? Curious what the final product looks like vs the prototypes

Also does anyone have pics or explain in detail how to remove the gas piston for cleaning.


Thank you

Here you go, did anyone else's come without a rubber butt pad? I think its strange that it doesn't have one.

Hello all! Been stalking the forum for about 2 years since the MPX was announced. Have a few others Sigs too (P226 TacOps TB, P938 Scorpion TB, P522 SWAT) but I haven’t wanted anything as bad as the MPX in a long time. Anyways…



@Prpratt I think yours is missing the pad…. Mine was delivered today and is waiting for me at home! I’ll look at mine tonight but if you look at the one on GunBroker http://www.gunbroker.com/Aucti....aspx?Item=488422612 the picture of it in the bag and on the desk has the rubber pad. Notice this has been bid up to $1,000!!! Somebody really wants this! Ironically this shop is right by my house.



Mine also has the charging handle issue. Comparing it to an AR it’s easy to see why it slops down. A regular AR the charging handle is the full height of the opening the entire length supporting it. The MPX one is cut to a shorter height in the middle which removes the support, but then is the full height at the handle part which is why it’s fully supported there. To me it seems that is just needs a new charging handle and one that is the full height just like an AR. I contacted several companies and suggested it. At this time no one is planning on making one, but AXTS (the company that makes the Raptor, one of the coolest looking AR ones out there) mentioned it was a possibility. So everyone should email them and request it! Maybe they’ll get the hint.



In regards to the trigger issue… This was one of the selling points for me that it took an AR trigger. Pretty bummed but plenty of people on YouTube and forums mentioned changing it without issues so far. Not sure this is going to stop me personally because the factory trigger sucks!

Thanks for the pic. Looks like that's the latest generation stock. I really like the 2nd gen better. Yes there should have been a rubber butt pad with that. Call CS tomorrow and they will send it out.

200 stock selling for 1200?!?

Someone really wants that thing.

Sig has had my mpx since Tuesday. We will see what they decide on the charging handle issue.

Well I called Sig to have the rubber butt pad that is missing sent but they do not have just that part in stock so I would have to return the whole assembly and hope that the 5 they have in stock right now don't sell between now and then. I opted to go ahead and purchase another stock and when it arrives I will return the original for a refund.

I spoke with John and he was very helpful and accommodating in all of this, his hands were just tied from taking the part I need off a new stock.

I hope to have it on Monday, hopefully my form 1 will come back by then too and I will be in business.

Are they still retailing for 200ish?

I was told the stock had gone to $299 but I had the 20% off coupon so it came to $239. The price I paid for the one that came without the butt pad was $191 after the 20% off.

One thing I forgot to mention. I did call Sig regarding mine to increase the counter by one on people who have the issue. They told me they were aware of the problem but they have only received “one” back for this issue (must be yours). He did mention the Band-Aid solution of using a piece of Velcro (shows he read the forum since that was mentioned here).

The exciting news is he stated they are working with Badger Ordinance on creating a solution but no idea on time line. I requested to be notified if they had a solution. He wasn’t sure if it would be covered under warranty or if the price would be discounted (20% similar to the other offer going on). I also sent an email to them requesting an updated charging handle to further encourage the idea but they never replied. Personally I’m still hoping for an MPX version of the Raptor but really I would buy the first one available.

Wow! Price already increased. Glad i got mine already. Bad news is according to the NFA tracker website, F-1's increased from 30 days to 90 days. So it might be a while yet...

Last week I got my 3 lug adapter from Trosusa.com and just installed it. Mark easy to work with. Great little adapter. Very well made and finished nicely. Only complaint is there was no spot for me to use a wrench to tightly. Other than that great adapter.

Before taking off the flash hider and after Adapter installed (Forgot it was Left Hand tightening, lucky remembered that quickly)
